    Thanks folks, that's what I was looking for.

    Yeah, didn't look stock but the center caps and lack of labeling made me wonder. They look like the Black Diamond model of the Maya MRS.

    That car HAS also had paint work, the front bumper is NOT from a LP640, it is a AFTERMARKET front lip.

    I've heard people saying not to change the wheels on the Lambo's due to safety reasons, would the Maya's be a safe wheel like the one's on this car??? I really do like those wheels a whole lot!

    The issue is the staggered fitment and overall rolling diameter on these wheel setups. Typically the aftermarket offers 8.5 x 19 FA with 245/30/19 and 13 x 19 with 355/25/19 or 13 x 20 with 345/25/20 RA.

    The Murcielago comes standard with 245/35/18 FA and 335/30/18 RA.

    To calculate overall tire diameter:

    (((cross section width x 0.aspect ratio) x 2) / 25.4) + wheel diameter in inches = overall tire diameter

    When one upsizes on wheel diameter, one compensate by using lower profile tires in an attempt to maintain the same overall tire diameter as stock.

    The Murcielago factory overall tire diameter is 24.75" front and 25.91" rear.

    Upgrading to 19" wheel and tire setup as noted above yields an overall tire diameter of 24.79" front and 25.99" rear

    Upgrading to a staggered 19/20" wheel and tire setup as noted above yields an overall tire diameter of 24.79" front and 26.79" rear.

    Looking at these numbers, the 19" setup maintains an overall diameter closest to the factory specs.
